Dataset Description

This dataset contains 1,000 coding and reasoning traces generated by the new Fable 5.1 model using max reasoning effort.

It holds almost 30,000,000 tokens of step-by-step chain-of-thought programming across multiple complex domains.

It has also been deduplicated and filtered to remove low-quality traces, keeping only high-quality traces.
